TP3094 COMBO
Quad PCM Codec/Filter
General Description
The TP3094 is a monolithic PCM Codec and Fil-
ter device implemented using a digital signal pro-
cessing architecture. It provides four voice
channels, combining transmit bandpass and re-
ceive low pass channel filters with companding A-
law or m-law PCM encoders and decoders. The
device is fabricated using National’s advanced
CMOS process.
The device includes anti-aliasing filters and sig-
ma-delta converters dedicated to each channel,
and by a common signal processing unit which
performs all the remaining filtering and process-
ing for the four channels.
The TP3094 includes a flexible PCM digital inter-
face, which allows the device to be connected to
PCM busses of different formats. It can also be
connected with other TP3094 devices in a cas-
cade fashion, for a system with up to 128 POTS
interfaces (when a 2.048MHz PCM bus is used).
